feat: store asset requests in shared JSON file

- Create public/data/asset_requests.json for shared storage
- Use Hugging Face API to update file when submitting/voting
- All users can see and vote on asset requests
- Use VITE_HF_TOKEN environment variable for security
- Agent submissions still use localStorage (admin only)
